Ok this problem occurs not just when playing multi-player but it just happened to me playing against the bots.

Waiting to begin Hand Number 8.

St3baS posts the small blind(R5).EvilFish posts the big blind(R10).Dealer deals the pocket cards...5� K� Shades put in R10 and meets the current bet.It is your turn to play.St3baS put in R5 and meets the current bet.EvilFish put in R564 and raised to R574.Shades went all-in with R17.It is your turn to play.St3baS put in R564 and meets the current bet.

Dealer shows the Flop...6� 6� 4� It is your turn to play.*At this point I tried to Click on BET and nothing happens... the message in the bottom left of the screen is "You called"*St3baS says: Messages are still working but nothing else is

And thats where it ends... maybe this will provide a bit more insight.
